Koithiro Motoyama

Title: Koithiro Motoyama and Color Television Camera Technology.

Introduction

Koithiro Motoyama is an inventor associated with Kanagawa, Japan, and Victor Company of Japan, Limited. His recorded patent concerns a color television signal-generating apparatus designed for use in a single camera.

Latest Patents

Motoyama’s listed patent, “Color Television Signal Generating Apparatus for Use in a Single Camera,” describes a system that separates a camera tube’s output into signals used to produce color television images. A striped color-resolving filter creates a composite signal containing direct-wave color information and a high-frequency component of modulated color signals. The apparatus separates these components and uses detectors to recover signals from the positive- and negative-wave envelopes of the high-frequency component. This approach was intended to support color-signal generation within a single-camera system. The available information lists 1 patent for Motoyama.

Career Highlights

Motoyama’s documented patent work is connected with Victor Company of Japan, Limited, a company known for its work in electronics and audiovisual technology. The patent reflects engineering efforts to process color information from a camera tube using a striped filter and signal-separation circuitry.

Collaborations

Sumio Yokokawa and Kenichi Miyazaki are identified as Motoyama’s coworkers. The available information does not specify their roles in developing or filing the patent.

Conclusion

Koithiro Motoyama’s recorded contribution is a single-camera color television signal-generating invention that uses filtering, signal separation, and envelope detection to recover color information.
